It is clear that we’re seeing the future use of ETN becoming a currency in exchange for goods and services by simply using our mobile wallets - Instant payment API. However, the mobile wallets do not operate without wifi and its the only option available at the moment.
Electroneum aims for mass adoption which includes the unbank presumably the majority of poverty/poor class citizens. Many who are unable to afford a monthly payment - phone service. Or in a case of a lost, broken or stolen phone. Common users will have to factor in a monthly expense for service - $50-100 monthly average (US). Technically, the Electroneum app is free but not the maintenance service.
-How will the user be able to use his/her ETN offline?
-Will, there be a form of a debit card?
Debit card - BitPay for example. A 3rd party service who provides a Visa card to Bitcoin users that can be used anywhere offline with $0 cost for monthly maintenance - free compared to mobile service. Users don’t need a mobile phone or wifi to access their funds unless they want to check their balance.
This is NOT FUD but a user concern/curiousity.!
I turned off both data and wifi to showcase the wallet app offline. If users could use the app without wifi/data. We don’t need a debit card or such. That would be a game changer!

Pundi X - a crypto company with a similar payment system as Electroneum. Possibly instant as well. However, not only do they offer vendor API but also an offline card without using your mobile phone - X Pass Card. Similar to a debit card or Bit pay.
Check out their video demonstrating the use of X Pass and mobile purchasing Coffee.
Disclaimer: I’m not an affiliate or investor of Pundi X. Just pointing out the “offline” issue and perhaps challenge the Electroneum team for innovative ideas to solve this problem.
